NTC bulb probe for radiant tubes

Man, plants and animals do not feel the temperature of the air but the radiant temperature, that is, the temperature radiated by cold bodies or by hot bodies. The air temperature is only "felt" by a third.

This "physiological" probe is equivalent to the sensitivity of the forehead or head of the occupants of an area or an entire industrial warehouse. It is therefore strongly recommended to choose the hottest point of the installation as the fixing position, which must generally be 1.80 meters from the floor.
